コンソール引数付のファイルを外部から実行する

subpro_qiita.py
import subprocess
from time import time

name_list = ["john","power","smith","jack"]

for i in name_list:
    print(i)
    # コンソール実行時の場合に空白で区切る部分を分割してリストに入れる"
    # python greeting.py --nickname XXXX の場合下記のようになる。
    command = ["python","greeting.py","--nickname", f"{i}"]
    proc = subprocess.Popen(command)

実行するファイル

greeting.py
import argparse
import time

def arg_res():
    parser = argparse.ArgumentParser()
    parser.add_argument('--nickname',required=True)

    args = parser.parse_args()

    nickname = args.nickname

    greeting_sentence = f"僕のニックネームは{nickname}"

    return greeting_sentence

def test_main():

    greeting_sentence = arg_res()
    print(greeting_sentence)

if __name__=="__main__":
    test_main()
